The pint-size pop star, usually in the news for bratty behaviour, has thrown his weight behind a new, worthy cause: Malala Yousafzai’s fight for girls’ rights in Pakistan and beyond.

The Boyfriend singer on Thursday posted a screenshot from a FaceTime chat with Malala, who was shot in 2012 for speaking out in support of education reform.

The 15-year-old survived the attack and started the Malala Fund to help empower young women around the world.

“Just got to FaceTime with Malala Yousafzai,” Bieber told his 19.5 million Instagram followers. “She has such an incredible story. I can’t wait to meet her in person and talk about how I can support her and the @malalafund.”

If he follows through, the Malala Fund will join as many as 16 charities and 20 causes worldwide that count Bieber as a supporter, according to the Daily Mail.

That makes him one of the charitable celebrities of our time — a fact often overshadowed by his bad boy antics — the newspaper notes.

Biebs wasn’t the only star to chat with Malala this week.

On Tuesday, Reese Witherspoon also posted a picture with the inspirational teen, saying she was thankful for the opportunity to meet her.

“What an honour to meet and have dinner with Malala Yousafzia @malalafund,” the 38-year-old wrote. “Thank you for your work on behalf of women everywhere.”
